Here's a revolutionary idea

There's an ongoing barney on social and mainstream media about what the latest poor numbers for business confidence might or might not mean, and, in that unappealing Kiwi way, who's to blame. The truth is, we're all reduced to guessing what goes through the minds of the people who fill out the survey forms and bung them back to the ANZ and the NZIER.

My conjecture - an upmarket way of saying 'sort-of-informed guess' - is that it's actually a mix of several things. There's probably an element of party politics in it, though as I said the other day, it looked to me as if the business community had got past the toys-out-of-cots stage. There's probably an element (beyond partisan) where they've looked at government policies and think they're bad news (irrespective of who introduced them). There's certainly concern about pressures on profitability, where there's pretty obvious evidence of costs pressures that aren't easy to pass on to consumers.

That's not hard, is it? You could ask the same questions here, word for word, and you'd be left with as clear an answer as the Aussie survey shows.

Just before I let go of this business confidence thing, could I say to all those talking up and talking down the 'confidence' figures, confidence readings are kinda interesting in their own right, but you're both paying them far too much importance. The links between 'confidence' and actual business outcomes aren't always that strong.

But don't extrapolate from that and say, business surveys are airy fairy indicators of nothing in particular. It is - and you can't say this terribly often in economics - beyond reasonable question that some of the measures in these surveys, particularly the ones related to firms' own prospects, have very strong links to reality. You might think a simple 'getting better/getting worse' question isn't going to get you very far. But it often will, which is why even official statistical agencies run them.

And, finally, here at home here's how a combo of some of the business and consumer measures in the ANZ business surveys track against our GDP (it's a graph in the latest one). It's a pretty good relationship. It helps too that it is timely, and a leading indicator of what's down the track (the graph shows a five month lead between changes in the indicator and subsequent changes in GDP).

So for all those knocking business surveys because it suits them tactically - give over. These are useful, cheap, timely and while not every bit of them is always telling you useful stuff, in parts and in combo they give reliable readings on where we are and where we're going. If the evolution of the economy, good or bad, is giving you political conniptions, don't shoot the messengers.

Welcome to my economics blog

“The remarkable thing about economics is that once you've been exposed to the big ideas, they begin to show up everywhere … Economics offers insight into wealth, poverty, gender relations, the environment, discrimination, politics...How could that possibly not be interesting?” - Charles Wheelan, Naked Economics: Undressing the Dismal Science, 2002

"The soundest argument for markets ... is simply that, very frequently, they are the least bad of the alternatives. To paraphrase Winston Churchill's remark on democracy, markets are the worst form of resource allocation, except for all the others that have been tried" - Prof George Yarrow, Three Lectures on Privatization, Jagiellonian University, Krakow, April 1990

"And if there's one thing we've learned about flawed markets, it's that people flee from them, either physically or by resorting to back channels and black markets. Either way, flawed markets can undermine not just communities but whole nations" - Alvin Roth, Who Gets What - and Why, 2015

"More than ever, the ideals of reason, science, humanism, and progress need a wholehearted defense...Problems are solvable. That does not mean that they will solve themselves, but it does mean that we can solve them ifwe sustain the benevolent forces of modernity that have allowed is to solve problems so far, including societal prosperity, wisely regulated markets, international governance, and investments in science and technology" - Stephen Pinker, Enlightenment Now: The Case for Reason, Science, Humanism and Progress, 2018

"Economic controversy is generally a thankless task. You cannot hope to make any impression on your opponent. Yet he is the only reader on whose interest you can count" - Francis Ysidro Edgeworth, Economic Journal, 1898

"There is some evil genius which sits at the elbow of every economist, forcing him into all sorts of contorted and unnecessary complications" - John Maynard Keynes, letter to Roy Harrod, August 1935

"We are here and it is now. The way I see it is, after that, everything tends towards guesswork" - the philosopher Didactylos, in Terry Pratchett's Small Gods, 1992

"I have never yet seen any plan which has not been mended by the observations of those who were much inferior in understanding to the person who took the lead in the business" - the blogger's creed, as foreshadowed by Edmund Burke, Reflections on the Revolution in France, 1790

"They acted as their situation naturally directed, and they who have clamoured the loudest against them would probably not have acted better themselves" - advice to Twitterati, as foreshadowed by Adam Smith, An Inquiry Into The Nature and Causes of the Wealth of Nations, Book IV, 1776
